Explanation:
Mass of starting material i.e Aluminium is 
grams
The weight of oxygen is 
There are 4 atoms of aluminium and 3 atoms of oxygen
Thus, the total mass of starting material is
mass of one atom of aluminium 
mass of one atom of oxygen
grams
Mass of new substance is also equal to
mass of one atom of aluminium mass of one atom of oxygen
grams
